Planet Source Beta-hydroxybutyrate (BHB) 2000 Beta-hydroxybutyrate (BHB) is a ketone body produced during fat metabolism, particularly when carbohydrates are scarce, such as during fasting or a ketogenic diet. It serves as an alternative energy source to glucose for the brain and muscles. BHB is often used in supplement form to help boost ketone levels in the body, enhancing mental clarity, focus, and physical endurance. A BHB supplement, often referred to as "exogenous ketones," can promote ketosis, a metabolic state where the body burns fat for fuel. This can be particularly beneficial for individuals following a low-carb or ketogenic diet, helping them reach and maintain ketosis more quickly. BHB supplements may also support cognitive function, improve athletic performance by increasing energy levels and stamina, and potentially aid in weight management by promoting fat burning. While BHB supplements are generally safe for most people, they should be used carefully, especially for those with existing health conditions. Always consult a healthcare provider before adding any supplement to your regimen.
